Reproduction of "ArgumentError: invalid byte sequence in UTF-8" webmock bug

webmock-bug.rb

#!/usr/bin/env ruby
require 'bundler/inline'

gemfile do
 source 'https://rubygems.org'
 gem 'webmock', '1.24.6'
end

include WebMock::API

stub_http_request(:get, /foo/).to_return(body: "abc")

begin
  Net::HTTP.start("example.com", 9000, use_ssl: true) do |http|
    request = Net::HTTP::Get.new('/foo')
    request['Authorization'] = 'Basic foo'
    http.request(request)
  end
rescue => e
  puts "ruby: #{RUBY_VERSION}-p#{RUBY_PATCHLEVEL} failed: #{e.inspect}"
else
  puts "ruby: #{RUBY_VERSION}-p#{RUBY_PATCHLEVEL} passed"
end

Running the above across various Ruby (MRI) versions:
